    Connect grid tied solar inverter to DC+ Bus of VFD?

    It is much easier than it sounds. We tried the wind turbine approach with capacitors, rectifiers and solar grid tied inverters. It works well with good energy yields, however, you require many failsafes to prevent damage to your equipment. Also a more expensive method with multiple components...

    Grid tied micro hydro using Pump As Turbine

    @Tom.G Off-the-shelf solutions are a bit pricey in my area, especially considering that we only have about 4 months of sufficient rainfall to keep the turbine running, so ROI would take a while! @Rive I was thinking that a VFD could be used to bump up the frequency of the AC, prior to...

    Connect grid tied solar inverter to DC+ Bus of VFD?

    Hi looking, I've read your post about feeding excess generated AC back to the grid using a solar grid tie inverter. I found it very interesting and similiar to what I am planning to do myself. Our irrigation ponds overflow during the winter causing soil erosion, so we installed a 160mm pipe...
